100% fit for purpose
Product is as described and works ok. It works 100% accurately with the paired Polar watch. It also works with gym fitness machines equipped with Bluetooth technology for HR reading (e.g. Life Fitness treadmill), but for some reason approx. after first 10 minutes of training, the HR indications on the machine start jumping up and down. I could not figure our why.

Precise
Delivery and service as expected. The HR sensor itself is precise, and is more reliable than my FitBit.

Connectivity issue :(
I'm concerned with the bluetooth connectivity on mobile as it keep disconnecting. Will call Amazon to accept return. Not impressed.

Präzise und absolut zuverlässig
Verbindet sich sofort mit ANT+ und Bluetooth, egal ob mit der Uhr oder Trainings-App. Die Messwerte sind konstant genau, auch bei intensiven Einheiten. Der Gurt sitzt angenehm und rutscht nicht. Für mich das beste Brustband in dieser Preisklasse.

Excellent heart rate monitor
Does it’s job. Simple setup and straightforward to use . Have been using for more than a month and has worked flawlessly. Mainly used while cycling and a few times for brisk walks. Heart rate readings are consistent without drop outs

Ottima fascia cardio - uguale al fratello H10
Ho comprato l'H9 poiché costa meno dell'H10 e per quello che ci devo fare va più che bene. Provato sul campo, funziona alla grandissima. L'ho usato per registrare l'andamento cardiaco in vari test, diversi tra loro: dal classico yoyo test, quindi corsa, a test per atleti di arti marziali (taekwondo). Funziona benissimo. Le funzionalità che ha in più il fratello maggiore (H10) a mio avviso sono inutili per il 99% delle persone che utilizzano amatorialmente questo tipo di prodotto o comunque non sono in grado di capirle e leggerle a dovere. Le rilevazioni dell'H9 sono fantastiche, oltre che la precisione di rilevamento, con le app giuste si può avere traccia persino dell'HRV. Questo giusto per sottolineare la potenza del dispositivo, ma ancora una volta, se non sapete che cosa sia o come si legga, non ha nemmeno senso usarlo. L'unico punto che un atleta o preparatore potrebbe davvero indirizzare l'acquisto di un H9 o H10, è la memoria interna. Ci sono sport o momenti in cui il collegamento con il cellulare o la possibilità di utilizzare uno smartwatch adatto non è fattibile e lì entra in gioco la memoria interna. Se nel vostro sport non vi muovete molto nello spazio o sé portarvi dietro il telefono è sempre possibile, l'H9 ha il 100% di validità per voi. Se invece avete lo smartphone non è possibile o difficoltoso e/o se il collegamento rischia di interrompersi, allora l'H10 è più indicato. Penso in particolare a sport come il nuoto, per cui l'acqua può fare da schermo al telefono (magari però avete uno smartwatch e il problema non si pone). Oppure anche all'arrampicata sportiva, dove avere il telefono non è sempre possibile o banalmente l' altezza e/o la roccia che fa da schermo inficia il collegamento. Personalmente facendo anche arrampicata sportiva su roccia (non boulder) mi sono trovato a dover restituire l'H9, proprio perché il collegamento su interrompe spesso e non possiedo uno smartwatch. Ne avessi avuto uno lo avrei tenuto senza alcun dubbio. Per tutto il resto, taekwondo, pesi, corsa, telefono+H9 funziona alla grandissima (e si capisce dopo pochissimo tempo quanto il plus dell'H10 sia veramente superfluo a chiunque). La fascia dell'H9 è molto buona, non scivola, facile da far aderire e aggiustare. La chiusura è diversa dalla fascia pro, ma è (s)comoda allo stesso modo. Sinceramente tutta questa differenza non la vedo, anzi.. Ricapitolando, se vuoi un cardiofrequenzimetro ottimo e non hai particolari esigenze sulla funzionalità, l'H9 è perfetto e ti fa risparmiare 20-30€. Se invece per qualsiasi motivo ti ritrovi ad allenarti senza la possibilità di portare il telefono \smartwatch o se devi nuotare, allora l'H10 è l'unica opzione, poichè può registrare un allenamento. ps in tutto questo sono convinto che l'H9 non sia altro che un H10 con limitazioni via software.

Capteur très bien mais boucle de ceinture mal conçue.
Les informations sont claires et précises. Excellent outil pour s'entraîner de façon cadrée. MAIS il faut choisir le modèle avec la boucle de sécurité avec poussoir plat à insérer (formes rectangulaires). Le système à crochet comme celui-ci saute tout le temps et la ceinture se détache très vite. J'achète les bonnes ceintures à part du capteur. Evidemment cela revient plus cher mais sans ça je ne sais pas travailler.

Perfect app; strap needs DIY modifications; works great with my old polar watch
The strap sucks. If you have no lats, maybe it won't slide down your body as you run. But for those of us with big lats, you have to modify this thing. You can either modify the strap, or buy the $40 Polar Pro chest strap (you’ll have to replace any strap you get probably every 6-12 months so keep that in mind). I haven't tried the outrageously-priced Polar Pro but it's the only one on the market that has grips all the way around the strap, not just in the front. The chest strap can be easily modified as follows: Buy one of the "zig zag silicone grip wave bands" you can find online, and sew it (or use fabric glue or something) to the inside of your Polar chest strap and it actually stays in place while running! Just make sure you get the strap customized to your underchest first, and give yourself some space for the inevitable long-term loosening of the strap (you might need to tighten it gradually over time). Without the extra grip, you have to find the perfect balance through much trial and error between too tight and too loose. Too tight, and it creates a little cavity where the electrodes are between the strap and your chest (so it gives you terrible readings, if any). Too loose, and it falls down to your waist. I also found that using a small dab of electrode gel on each of the two electrodes on the back side of the chest strap (enough to cover just the two circles on the strap where the strap touches your chest) makes a huge difference in getting a consistent, accurate, read. Don't use water, it just doesn't work nearly as well. I love the Polar Beat app it comes with! It was the best free app I could find for Android for a heart rate monitor. I'm sure there are probably better paid ones out there but I didn't try any of them so can't attest. The Polar Beat app gives you a graph at the end of your workout that shows your heart rate over time, and tells you how many minutes and seconds you spent in each of the 5 heart rate zones (50%-60% of max heart rate = zone 1; 90-100% = zone 5). It has certain modes that track your GPS location for accurate maps of your runs/rides and the app will tell you every mile when running how long your mile took, your pace, and average heart rate. I've never used it for a bike ride. It also tracks calories very well and whenever it doesn't get an accurate read, it does a pretty good job "guessing" (better than the old Polar Watch I have). If I start my workout on the Polar app first, THEN start the workout on my Polar watch, it will let me use both to track my workouts which is great. That way I can leave my phone in my gym bag while running around the track, and use the watch instead to track % of max heart rate. It's also nice when using my phone for anything else while I'm doing a HIIT circuit or on the exercise bike, that way I can just look at my watch to see my stats. I don't have a smart watch so can't comment on how it works with that. I think you might need to get the latest and greatest to pair it to two or more smart devices at once. But this one works perfectly for one smart device and one dumb device.
